MARINE POWER INSTALLATION.

Original No. 1,667,475, dated'April 24, 1928, Serial No. 186,361, filed April 25, 1927. Application for reissue filed December 22,

My invention relates to power developing apparatus, more particularly to marine propulsion systems, and has for its. object'the provision of apparatus of the character designated which is capable of developing relatively high power and which may be readi ly installed in a limited space in a vessel.

More specifically, the object ofmy invention is to provide means for transmitting power from one or more internal combustion engine units, each embodying a closed series of cylinders defining a polyhedron, to a propel.- ler shaft in such a manner that the engines may be arranged with respect to the ships structure so as to occupy a minimum of space; I Apparatus embodying features'of my invention is illustrated in the accompanying drawings forming a part of this specification,

wherein Fig. l'is a plan view showing my improved marine propulsion system as applied to a- S i 5 Fig. 2 is an elevational View of the apparatus shown in Fig. lwith parts of the ships hull broken away;

Fig. 3 is an end elevational view, partly in section, of the gearing employed with one of the engine units according to my invention;

Figsr4 and 5 are diagrammatic views showing the arrangement of gears for other positions of the engine units with respect to the ships hull; and,

Figs. 6 and 7 are diagrammatic views of the arrangement of gears according to my invention as applied to a six-sided and an eightsided engine, respectively.

My invention is particularly applicable to marine installations employing internal combustion engine units having cylinders arranged to describe a polyhedron and of the type disclosed in the application of Herbert T.

Herr, Serial No. 86,494, filed February 6, 1926, and assigned to the Westinghouse Elec. & Mfg. Company, although it will be apparent that it may be employed with e ual facility with other types of engines, Wit engines of the character described in the aforesaid application, the c linders surround the propeller shaft with t e shaft disposed centrally of the polyhedralv frame of the engine and I power from the cylindersistransmitted to the propeller shaft through the intermediary of suitable gearing.

While such an installation is ideal from the 1928. Serial No. 328,020.

point of View of generating and'trarismitting sel, the dispositions of a plurality of such en gines with their cylinders around the pros peller shaft may take up considerable, much needed room. My invention therefore consists primarily in a system of gearing for engines of the character described whereby the point at which power is transmitted from the engine to the propeller shaft may be located in various positions with respect to the axis of the engine frame. More specifically, I transmit power from the engine cylinders to the propeller shaft through a system of gearing including idler gears, in such a manner that the major portion of the engine frame may be so located with respect to the propeller shaft as to accommodate itself to the shipsstructure and thus take up a minimum of room.

Referring now to the drawings for a better understanding of my invention. I show, in Figs. 1 and 2, a fragment of ships structure including side structure 10 and bottom structure 11. The vessel is propelled by a pair of propellers 12 and 13, said propellers being inclined rearwardly and outwardly from the vessel. Each of the propellers is driven from a plurality of polyhedral engine units such as 16, 17 and 18, allgeared to a common propeller shaft 19. It will be noted from a consideration of Figs. 1 and 2 that the engine units 16-,- 17 and 18, as well as the associated units driving the propeller 13 are so arranged with respect to their respective propeller shafts that they are relatively closely spaced with respect to the ships side andbottom.

Referring now to Fig. 3, each of the engine units comprises a closed series of similar cylinders such as 21, 22, 23 and 24. In each of the cylinders are a pair of opposed pistons pistons of the cylinder 23 are connected to crank shafts, with the remaining pistons of the cylinders 22 and 24 (not shown). It will be seen from the foregoing that the

cylinders

21, 22, 23 and 24 comprise a polyhedron having crank shafts at'the' vertiees thereef- Connected to the crank shafts of the engine are four driving gears 31, 32, 33 and 34 which transmit power developed in the cylinders to a driven gear 36 connected to the propeller shaft 19, the propeller shaft being positioned by means of bearings 37, shown in dotted lines behind the driven gear 36, and suitably secured to a plate member 38 which is apart of the'engine frame.

The propeller shaft may paitly support the engine, In the example shown, the engine is at least partly supported from the ships bottom structure as by means of suitable supports 41and 42. It will be noted from a consideration of Fig. 3 that should the engine be so located with respect to the propeller shaft 19 that the shaft would'be centrally of the engine frame axis, that the engine would occupy a position more to the left of that shown in the figure and would thus probablyinterfere with the positioning of the engines on the other sideof the vessel. Furthermore, it

would leave vacantfa space near the ships hull, toward. the right of the figure, which would serve no useful'purpose.

It is to overcome this peculiar difficulty that my invention isp-articularly directed. Inorder that the engine may occupy a position as close to the side and. bottom structure of the vessel as may be desirable, I interpose between the driving gears 29 and 33, and the driven gear 36,a pair of idler gears 43 and 44. V The power from the gears 31 and 34 is transmitted directly to the driven gear 36, while power from the gears 32 and 33 is trans mitted through the idler gears 43 and'44. The effect of the idler gears 43 and 44 is to displace the engine frame with respect to the propeller shaft so that it may be more closely located with respect to the ships side and bottom. It 'will furthermore be apparent from Fig. 3, thatsmy improved gearing means permits the inclination of the engine with respect to the horizontal so that'it may more readily conform to the ships side.

In Fig. 4, I show, diagrammatically, the; arrangement of gears for the engine 16. a In this

view driving gears

51 and 52 transmit power to a driven gear 53 through the intermediary of a pair of

idler gears

54 and 56, while driving

gears

57 and 58 transmit power directly to the driven ear 53. With this arrangement, the propel er shaft is located in a position with respect to the engine frame 19, below the axis of the engine frame.

In Fig. 5, I show an arrangement of gearing forthe engine, similar to that in Fig. 3, but wherein it is not necessary to tilt the engine frame in order to accommodate it to I the ships side such as is shown in Fig. 3. In

this figure, driving gears 61 and 62 transmit power to a driven gear 63 through the intermediary of

idler gears

64 and 66, while driving gears 67 and 68 transmit power directly to the driven gear 63. From the examples given, it will be plain that this improvcdgearing arrangement may be so applied to an engine of the character described in transmitting power to the propeller shaft, that the engine frame may be located in a variety of positions with respect to the propeller shaft and so to accommodate the engine structure to the space allot-ted.

In' Fig. 6, I show diagrammatically a polyhedral engine comprising a closed series of six

cylinders

71, 72, 73, 74, 75 and 76. The pistons within the cylinders 71 to 7 G inclusive are connected to

driving gears

81, 82, 83, 84,

85 and 86, respectively. In the example shown, the driving gear 82 transmits power to a driven gear- 88 through the intermediary of an idler gear 89, while the

driving gears

81 and 86 mesh directly with the driven gear 88. The driving gear 85 transmits power to a driven gear 89 through the intermediary of .an idler gear 91, while the

driving gears

84 and 83 mesh directly with the driven gear 89,

and the driven gear 89 meshes with the driven gear 88. In the arrangement of gearing such as is here shown, power may be transmitted from the engine through either of the driven gears 88 or 89 and the shaft for either of these gears may be included in the propeller shaft. .In Fig. 7, I show yet another modification of my invention wherein there is employed a polyhedral engine embodying a closed series of eight

cylinders

101, 102, 103, 104; 105, 106,

107 and 108. The cylinders 101 to 108 transmit power through a series of driving

gears

109, 110, 111, 112, 113, 114,115 and 116, re-' spectiyely. The driving gears 111 and 112 mesh directly with a drlven gear 121 while .the driving gears and .113 transmit power to the driven" gear 121 through the intermediary of idler gears 122 and 123. The driving gears and 116 transmit power directly to a driven gear 124 which meshes with the driven gear121, while the driving gears 114 and 109transmit power to the driven gear 124 through the intermediary of idler gears 126 and 127. In this arrangement the power from the engine may be transmitted through either of the driven

gears

121 or 124 and the propeller shaft may be located coincidental with the shaft of either of these gears. With either arrangement, it will be seen that the major portion of the engine frame will be to one side of the propeller shaft and that the engine may be so disposed in a ships hullas to accommodate itself to the space allotted.

, From the foregoing, it will be apparent that I have devised an'improved marine propulsion system, whereby the power units of such systems may be the most advantageously disposed with respect to the ships propeller shaft and the ships structure.

While-I have shown my invention in several forms, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modi-- fications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.
